상황
A user needs a 0–300 Hz high-current pulse generator to drive an electromagnetic hammer from a 12 V DC supply, using a MOSFET as the final switching element.

그 이면의 의사결정을 읽어 보세요.
01
Use a classic two-transistor astable multivibrator as the adjustable pulse source
02
Drive an N-channel MOSFET in low-side configuration to switch the electromagnet coil
03
Include a flyback diode and gate pulldown resistor to protect against inductive kickback and floating gate
Reusable for solenoid drivers, vibratory feeders, electromagnetic hammers, or any low-frequency high-current inductive pulse application where a fixed or tunable repetition rate is needed.
